Overview
Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.

FEMALE—Length 9 mm.; black, tegulae and tarsal segments testaceous, tibiae and femora testaceous in part, with dark infusions, mandibles dull ferruginous, antennal scape somewhat reddened apically, the tubercles entirely black; lateral ocelli separated from margin of vertex by about half their diameter; cheeks about half width of eyes, rather strongly narrowed below, posterior margin carinate; segments of antennae only slightly longer than broad, segment 2 slightly longer than 1; median length of labrum slightly more than half the breadth, with a pair of subapical, carinate denticles; posterior margin of scutellum rather strongly rounded, quite deeply impressed medially, free part of axillae quite short, acute, reaching slightly beyond mid transverse line of scutellum (similar to lunatus, fig. 112) ; wings hyaline basally, lightly infuscated apically, veins brownish-testaceous, transverse cubitus incomplete, thus with only two submarginal cells; face with considerable pale tomentum, rather dense between antennae and eyes, very short but evident on clypeus, largely hiding surface, and rather dense on cheeks; margin of pronotum quite densely pale tomentose, tubercles with a similar fringe, and upper adjacent area of pleura quite densely whitish tomentose; scutum with a pair of elongate patches of pale tomentum on each side of mid-line anteriorly, lateral margins narrowly tomentose, continuing around the scutello-mesothoracic suture; metanotum and adjacent margin of scutellum rather thinly whitish tomentose, with a tuft of elongate white hairs at each end, posterior face of propodeum on each side of triangle rather thinly white tomentose; basal abdominal tergum with a broad, transverse, black tomentose area which is bordered anteriorly and posteriorly with dense whitish tomentum, these rather broadly joining at each extreme side; terga 2-4 with transverse, apical, tomentose fasciae, with oblique patches of pale tomentum on each extreme side of tergum 2 that join the apical fascia; tergum 5 with rather extensive areas of dense, whitish tomentum on each side of pseudopygidium; tegulae minutely and closely punctate on inner side, becoming impunctate along outer rim; upper part of face rather coarsely, deeply and closely punctate, the punctures somewhat finer and partially obscured on cheeks, very fine and largely obscured on lower part of face; scutum, scutellum and axillae densely rugoso-punctate; lower portion of pleura coarsely and rather irregularly punctate, with a few shining interspaces evident, punctures becoming densely crowded above; discs of abdominal terga very finely, closely and quite regularly punctate beneath the black tomentose areas; pseudopygidium abruptly truncate apically, apical width somewhat greater than median length, covered with very short, fine, suberect bristles; sternum 5 strongly convex as seen in ventral view, somewhat narrowed apically.

MALE—Answers in general to description of female, but labrum, mandibles, tubercles tegulae and legs rather bright testaceous; scutellum somewhat more deeply grooved medially; terga 5 and 6 with conspicuous, whitish, apical, tomentose fasciae; sterna 4 and 5 with subapical fringes of elongate, somewhat curved bristles; pygidial plate strongly elevated above disc of tergum 7, apical part somewhat narrowed and elongate, rather broadly rounded, margins carinate, and surface with a few shallow, obscure punctures.

DISTRIBUTION—Wisconsin.
